Abstract: A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.

Abstract: A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.

Abstract: A prosthetic heart valve for implantation within a native atrioventricular heart valve. The prosthetic heart valve includes a self-expanding frame having an annular main body and a valve member disposed within the main body. The prosthetic heart valve includes an atrial sealing member formed by a fabric cover and a plurality of arms that are arranged side-by-side in a circumferential direction around the main body. The atrial sealing member extends radially outwardly from the main body and a peripheral portion of the atrial sealing member curves upwardly for conforming to surrounding native anatomy. The prosthetic heart valve further includes one or more ventricular anchors extending from the main body for capturing native leaflet tissue and thereby securing the prosthetic heart valve within the native atrioventricular heart valve.

Abstract: A self-expanding prosthetic heart valve includes an inner frame and an outer sealing frame. A lower region of the outer sealing frame is coupled to a lower region of the inner frame. At least a portion of the outer frame has a D-shape cross-section for conforming to a shape of a native heart valve annulus. Elongate anchors are positioned outwardly from the outer sealing frame for anchoring to native leaflets. Preferably, the native leaflets are secured between the anchors and an outer surface of the outer sealing frame. A valve body is positioned within an interior lumen of the inner frame and provides a one-way valve mechanism for replacing the function of the native leaflets. For additional stability, a further anchoring mechanism may extend from the inner frame for attachment to a heart wall. The prosthetic heart valve is well-suited for replacing the function of a native tricuspid valve.

Abstract: A prosthetic spacer assembly includes a spacer body, a first anchor, and a second anchor. The first anchor and the second anchor are each connected to the spacer body. The first anchor is configured to capture a first native valve leaflet between the first anchor and the spacer body. The second anchor is configured to capture a second native valve leaflet between the second anchor and the spacer body. When inside a delivery sheath, the first anchor and the second anchor can extend distally from the spacer body.

Abstract: A prosthetic valve assembly includes a support structure and a valve component. The support structure includes a first frame and a sealing member. The first frame includes a lumen extending between inflow and outflow ends. The sealing member extends inwardly into the lumen of the first frame and includes a first end wall defining a first orifice, a second end wall axially spaced from the first end wall and defining a second orifice, and an inner sleeve extending axially from the first end wall to the second end wall and spaced radially inwardly from the first frame. The valve component includes a second frame and a valve structure supported inside of the second frame for permitting blood flow through the valve component in one direction and blocking blood flow in the opposite direction. The valve component is configured to expand within and engage the inner sleeve of the sealing member.

Abstract: An implant includes an interface and a wing that is coupled to the interface. A catheter is transluminally advanceable to a heart chamber upstream of a heart valve of a subject and houses the implant. A delivery tool comprises a shaft and a driver. Via engagement with the interface, the shaft is configured to (i) deploy the implant out of the catheter such that, within the chamber, the wing extends away from the interface; and (ii) position the implant in a position in which the interface is at a site in the heart and the wing extends over a first leaflet of the valve toward an opposing leaflet of the valve. The driver is configured to secure the implant in the position by driving an anchor through the interface and into tissue at the site. Other embodiments are also described.
